QI/ for the (3m*2m) footing shown in fig. below find the column load (v) that can be carried by the footing using F.S.=3. V= ? 3x2 m B 3m $ = 20° e z0-8 Gs = 2-7 C=30 ANIm? Y= 19 kN/m3

B Calculate the ratio of the Ultimate Shear Force to Shear Capacity in one-way shear. Consider critical case only. A rectangular footing has dimensions shown and is acted upon by a dead load of 653 kN and a live load of 647 kN. The column dimension is 269x677 mm where the shorter dimension is parallel to B. The thickness of the footing is 442mm. f'c-28 MPa and fy=420 MPa for diameter 20mm bars. A=2.9m and B=4.8m

Subject: Principles of Foundation Design (Use NCSP) A rectangular footing is to be used to support a 300x400 (*400mm side is parallel to the long dimension of the footing) column loaded with 420 kN dead load and 540 kN live load. One side of the footing is 4.0m. Use effective soil pressure of 70 kPa. f'c=35 MPa and fy=420 MPa. Use minimum steel ratio for longitudinal bars as 0.0018. •Calculate the required thickness of the footing (mm) based on wide beam shear. db=16mm. Size of footing should be multiples of 10mm (Answer: 300) •Calculate the required thickness of the footing based on two-way shear. db=16mm (Answer: 430) • Calculate the required number of 16mm bars along long direction. . Use the governing thickness based on shear requirements. (Answer: 22)
